SCREENING FOR DEFECTS IN EMBRYOS IS FOUND TO BE HIGHLY UNRELIABLE
"[PGS] is based on the concept that the entire chromosomal constitution of an embryo can be represented by a single cell, which is removed from the embryo. If one biopsied cell is found to be abnormal, there is a 90% chance that the rest of the embryo is also abnormal or mosaic, where two or more cells with different chromosomal constitution exist in a single embryo."
Well it seems that embryos have the ability to self-correct.
"We found that embryos which were abnormal on day 3 demonstrated a high rate of mosaicism However, on day 5 some of them had undergone 'self-correction' into normal embryos. Others kept the same abnormalities, while some had acquired additional chromosomal abnormalities", she says."
"The timing is significant because embryos used in IVF are normally transferred at between 3 and 5 days old". SCIENCEDAILY
If you recall a British clinic was recently approved to use PGS in order to to weed out children with cosmetic defects and even those who would squint.
More death and destruction of life in the name of progress.
